The True Effect of Corona on the DNS

In recent weeks we've seen a range of press articles, security blogposts and public statements addressing real or perceived issues with network capacity and the domain name system (DNS) in particular. These range from concerns about the resilience of the DNS with questions on the impact of the number of registrations to news indicating that a tidal wave of fraud and abuse is hitting the world. more

The Early History of Usenet, Part III: File Format

When we set out to design the over-the-wire file format, we were certain of one thing: we wouldn't get it perfectly right. That led to our first decision: the very first character of the transmitted file would be the letter "A" for the version. Why not a number on the first line, including perhaps a decimal point? If we ever considered that, I have no recollection of it. more

Blocking Amplification Attacks: Sometimes the Incentives Work Against You

Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more

LEO Broadband Will Create Millions of Jobs

Earlier this month, Elon Musk tweeted an invitation to a job fair at the new SpaceX production and launch facility near Boca Chica, Texas. As shown here, the tweet says they want hard-working, trustworthy people with common sense. They are not looking for specific skills or education, but certain character traits – "the rest we can train." That tweet reminded me of hiring practices when I graduated from college. more

IGF 2015 Takes Action, Developing Best Practices to Address Internet Issues

After many months of hard work and preparation, the IGF community has published draft Best Practices on a range of key issues, complementing other intersessional efforts such as Policy Options for Connecting the Next Billion, and Dynamic Coalitions. Best Practices Forums (BPFs) offer the Internet governance community tangible ways to address Internet issues. more

Troubling Efforts to Distort and Undermine the Multistakeholder Process

ICANN's request for comment on amending the .com registry agreement to restore Verisign's pre-2012 pricing flexibility ended last Friday and, with 8,998 responses submitted by stakeholders, may have been a multistakeholder version of the St. Valentine's Day Massacre. Public interest in .com pricing is understandably high but the sheer volume of responses – nearly three times the number of comments submitted this summer on deregulating .org pricing – also suggests a show of force... more

Justice Department Recommends That the FCC Deny the Proposed ARCOS Cable Segment Connecting Florida and Cuba

In September 2020, I wrote a post on a proposed 56-kilometer link between the ARCOS undersea cable and the north coast of Cuba, near Havana. The Trump-appointed Justice Department Committee for the Assessment of Foreign Participation in the United States Telecommunications Services Sector was to conduct a 120-day security review of the proposal. more

Traditional Big ISPs Stagnate

In the first quarter of this year, the big cable companies added 482,000 customers, while telcos added over 50,000 customers. In what is a surprise to the industry, that growth has disappeared, and all of the big ISPs collectively lost almost 150,000 customers. That's a loss of 60,000 customers for the cable companies and 88,000 for the big telcos. The following statistics have been compiled by the Leichtman Research Group, which tracks the broadband performance of the largest ISPs in the country. more

The Future of the Internet From the Perspective of a NextGen@ICANN 78

This year, the 25th anniversary of the creation of ICANN was celebrated. The date carries a commemorative meaning, highlighting the trajectory of this institution that has been fundamental in the coordination and administration of Internet resources. However, this milestone also highlights the growing challenges facing Internet Governance in the current global landscape. more

WHOIS Disclosure Questions

In 2020, the ICANN Generic Name Supporting Organization (GNSO) Council approved a plan to revamp the WHOIS system as per the recommendations given by the ICANN Expedited Policy Development Process (EPDP). This plan directed ICANN to develop a centralized System for Standardized Access/Disclosure (SSAD) for WHOIS records. After much debate regarding the suitability and cost of such a system, ICANN brought together a group... more

The US-China Cold War in Cyberspace

In 2019 and 2020, the economic conflict between the US and China reached a peak. There was a months-long tariff battle that is still not fully resolved. After blocking Chinese-centered equipment manufacturer Huawei from its own markets, the US pushed hard to get the Five Eyes and all of its allies to block Huawei from foreign markets, too. Then the US started blocking its own companies... more

The Growth Rate of Broadband Speeds

Cisco has changed the name of its periodic predictions of broadband usage from the Visual Networking Index to the Annual Broadband Report, and recently issued a report that covers the period from 2018 to predictions made through 2023. Cisco is one of the few industry players that projects future broadband usage. Their past reports have been spot on in terms of predicting future broadband usage. more

The Huawei Issue in the Broader Context of Global Politics

It is very sad to see that Huawei has become a victim of US-China trade war politics and it will be very interesting to see how their court case against the US Government will pan out, the company claims that the ban of its products is "unconstitutional." There is no indication that Huawei has been involved in any spying activity; nor does it appear to have any intention of doing so. more

Do Not Track: Not as Simple as it Sounds

Over the past few weeks, regulators have rekindled their interest in an online Do Not Track proposal in hopes of better protecting consumer privacy. ... There are a variety of possible technical and regulatory approaches to the problem, each with its own difficulties and limitations, which I'll discuss in this post. more

Is There a Business Case for Fast Cellular?

We've gotten a glimpse of the challenges of marketing faster cellular usage since the two major cellular providers in South Korea made a big push in offering ultrafast cellular broadband. South Korea has two primary cellular carriers – SK Telecom and KT – and both have implemented cellular products using millimeter wave spectrum in Seoul and other dense urban areas. more
